Basic CMSIS Example
+
+
+

A typical example for using the CMSIS layer is provided below. The example is based on a STM32F10x Device.

+
#include <stm32f10x.h> // File name depends on device used
+
+
uint32_t volatile msTicks; // Counter for millisecond Interval
+
+
void SysTick_Handler (void) { // SysTick Interrupt Handler
+
msTicks++; // Increment Counter
+
}
+
+
void WaitForTick (void) {
+
uint32_t curTicks;
+
+
curTicks = msTicks; // Save Current SysTick Value
+
while (msTicks == curTicks) { // Wait for next SysTick Interrupt
+
__WFE (); // Power-Down until next Event/Interrupt
+
}
+
}
+
+
void TIM1_UP_IRQHandler (void) { // Timer Interrupt Handler
+
; // Add user code here
+
}
+
+
void timer1_init(int frequency) { // Set up Timer (device specific)
+
NVIC_SetPriority (TIM1_UP_IRQn, 1); // Set Timer priority
+
NVIC_EnableIRQ (TIM1_UP_IRQn); // Enable Timer Interrupt
+
}
+
+
+
void Device_Initialization (void) { // Configure & Initialize MCU
+
if (SysTick_Config (SystemCoreClock / 1000)) { // SysTick 1mSec
+
: // Handle Error
+
}
+
timer1_init (); // setup device-specific timer
+
}
+
+
+
// The processor clock is initialized by CMSIS startup + system file
+
void main (void) { // user application starts here
+
Device_Initialization (); // Configure & Initialize MCU
+
while (1) { // Endless Loop (the Super-Loop)
+
__disable_irq (); // Disable all interrupts
+
Get_InputValues (); // Read Values
+
__enable_irq (); // Enable all interrupts
+
Calculation_Response (); // Calculate Results
+
Output_Response (); // Output Results
+
WaitForTick (); // Synchronize to SysTick Timer
+
}
+
}
